Let's fiddle with the version matching such that it works with this VBT (i.e. treat BIOS v110 as having the same size as v108). Fixes [drm:intel_bios_init] *ERROR* Unexpected child device config size 27 (expected 33 for VBT version 110) Whether this is correct, no one knows - but it works for this particular machine.
